I created a basic textured cube model with Blender to practice modeling, and then I imported it into Unity. After I put up some lighting it looks pretty ugly. The light is not continuous on a row of textured cubes:

What is more odd, the light on the blocks that makes up the floor is continuous. What am I doing wrong?

UPDATE

This is how it looks like without textures: https://dl.dropbox.com/u/45620018/without%20textures.PNG

If I would not know that these are perfect cubes, I'd say there is a slight curve on surface. I also tried lightening the texture but it also didn't help: https://dl.dropbox.com/u/45620018/lighter%20texture.PNG

I just simply exported the model from Blender and did not set up any normals or things like that. However I also did not do any special woth the floor brick model.
